Knee: The knee is a joint which has three parts. The thigh bone (the femur) meets the large shin bone (the tibia) to form the main knee joint. This joint has an inner (medial) and an outer (lateral) compartment. The kneecap (the patella) joins the femur to form a third joint, called the patellofemoral joint. The patella protects the front of the knee joint.
Two major areas in the brain affected by autism are Wernicke's Area and Broca's Area (Carlson, 1999). Some other areas studied shown to be affected in autistic patients include the limbic system, cerebellum and association cortex.
Since auditory information is processed in the hippocampus, in people with autism the information may not be properly transferred to long-term memory. Auditory processing problems might be linked to other autistic characteristics, such as anxiety or confusion in social situations, and inattentiveness.
